IMO, no need to drill #1 main as it is fed right off the pumps main feed vs the others that get fed off the upper lifter gally. I like the idea of drilling between the lifter bores. One it helps get rid of extra oil there and two it directly drips oil on the cams lobes. The negative would be the extra oil dropping into the reciprocating mass. But, I believe that is a misconception in a race car. I feel that during acceleration most of the oil is thrown and drained down at the back of the motor. IMO, it only drains extra oil around the lifter bores , if the holes were drilled as you described at idle and cruise. Witch would help lubricate the cams lobes better in that enviroment. My block is currently drilled like that.

And what, the oil dripping through those great big windows in the valley don't hit the lobes ?!?!?!?

Oh no, without the holes oil will indeed spill over those big windows as you suggest. But where, maybe in just a few centralized spots. Not directly on every lobe. Hence the reason I used the word directly.
Now I didnt drill the holes around my lifters, they were already there. For my purposes I like them.
And For Daves purpose, I can see why he would want zero oil spilling into the reciprocating mass. For me, Im keeping my direct feed drip holes.  Even though they may have no absolute benifit
With all the flat tappet cam lobe wipeouts we here about, I want all the lube I can dripping on them at idle and cruise.

Ok so I did't think we would need to do number 1 but I thought I throw that out there  I think I will skip the holes in the valley. and I always clock the cam bearing so the holes only haft line up..easy restrictor .Not number 4
Number 4 has issues in itself because it robs oil from the crank bearing #4 and rods 6/7 to feed the valvetrain.
Member, Trendz, posted a great fix for this with pics, in the old power adder forum. I duplicated it on my engine as well.

And this fix was ??
Jamie, I just searched/found and Bumped Trendz description of it. Its actually Feets old thread titled " Any 440 block or crank failures with boost.

To be honest. the oil that slips past the lifter
(lifter/bore area) lubes the lifter plenty.. if you
think about it, its more than the little EDM hole
in the lifter and it falls right on the lobe

I agree, the oil that slips past the lifter should be plenty. A little extra wont hurt if it falls/drops from the topside.
Further, are you stating that the EDM lifters are worthless, and produce no more lubrication from the oil that slips past the lifter bore area.

I have a set of EDM roller lifters on my street rod
engine so I'm HOPING it adds a little more oil at
idle.... my opinion, at revs theres plenty of oil
just from the lifter/bore area

someone just posted this in other thread.
Back in the day we were all running huge oil pans in superstock. Most of them were Frankenstein homemade creations that did not leave a lot of ground clearance. Right about the time there were rule changes allowing big roller cams, larger tires ect,the big oil pan became a problem due to more wheel stands and oil pan carnage. Along came the synthetics. Just about everyone went to smaller oil pans with the new oils, the thought was that there was more protection and it was alright to run 6 to 7 qts. I started to have a large problem with oil pressure loss on decel. After fooling around with different baffles,trap doors,scrapers and windage trays,nothing seemed to totally eliminate the problem. Finally, I decided to look at the engine and any place I could drill a drain hole in the lifter valley near the cam tunnel I did with a 9/32" bit and a 1/2" chamfer. I had heard other people were doing this. Never had a problem again. I'll bet close to a qt of oil sits up there after a run( smallblock). Most of you guys are probably aware of this, I was just throwing it out there.

The EDM hole in a roller lifter is there to oil the roller bearings, not the lobes. Why would a roller cam need oil on the lobes, its a roller !!! Well, ok, you probably wouldn't want the lobes completely dry but they sure don't need as much as a solid or hydraulic cam.
Anyhow, to the point, WAY more oil flows out around the lifter than through the edm hole - so much in fact that if you prime your motor with the valley try off and watch the oil flow you'll wonder what the hell is going on!!

I was meaning to oil the bearings... from what I have
learned/heard the low idle is rough on oiling the bearings
EDIT
we didnt lose cams/lifters due to LACK of oil.. its
whats not in the oil anymore.... or at one time it
was poor lifters

I've worked on and seen some fo the old Rod Shop SS/AH motors that they tapped and installed a oil restrictor in the oil galley between the mains and the cam bearings
